Guitar Flash Games for a 12-Year-Old: HTML5 Rhythm & Learning Tools (Flash Is Dead)

Note: Flash is dead (since 2020). These suggestions are for HTML5/web-based or downloadable games that run today:

Rhythm / Guitar Hero-Style (Browser/HTML5)

• Guitar Hero Flash clones — many ported to HTML5 on sites like CrazyGames, Poki, Y8.
• Friday Night Funkin' (web/desktop) — open-source, moddable, great rhythm practice.
• Rhythm Doctor (demo on web) — one-button rhythm, clever design.

Educational / Real Guitar Learning

• Yousician (app/desktop) — listens via mic, teaches chords, tabs, songs. Free tier limited.
• JustinGuitar (website/app) — structured free lessons, highly recommended.
• Rocksmith+ (Ubisoft, sub) — uses real guitar via cable/interface; best "game" for real skill.

Creative / Sandbox

• Chrome Music Lab — browser toys for rhythm, melody, harmony.
• BeepBox / Bosca Ceoil — browser chiptune trackers.

Tip: Avoid old Flash-only links. Stick to HTML5, apps, or Steam/itch.io downloads.
